It is v primarily within the contemplation of my invention to enable wire templates to be readily formed for any desired pipe installation, whereby no welding or permanent securing together of the template wires need be resorted to. And in this aspect of my invention it is another object to enable the wires to be detachably connected, so that they may readily be disassembled after the templates are formed. and as readily reassembled thereafter in accurate manner, at any trating the use of my adjustable clamping-disk.

convenient place where theactual pipes are to be formed.

It is further within the contemplation of my invention to provide convenient means for enabling wire templates to be accurately formed for Y and T and other juncture connections.

Another object of my invention is to provide means for establishing accurate centers for the running of template wires for various types of pipe installations. And it is my further object to enable the aforesaid objectives to be attained whereby pipe installation work can be readily and accurately effected with the employment of a minimum of time, efiort and material.

Other objects, features and advantages will appear from the drawing and descriptions hereinafter given."

Referring to the drawing:

In the drawing, and particularly in Figures 1 and 2 thereof, is illustrated a layout of wire templates disposed between pipe fittings associated with the bulkheads and deck of a ship. The templates are arranged for pipe connections between the flange III of pipe ll attached to bulkhead l2, and the flanges l3 and ll of the pipe fittings l5 and |6, respectively, secured to the deck I1; and a template arrangement is also provided for connection between the flange l8 of fitting l5 and the pipe l9. In the specific layout illustrated, the template wire 20 is employed to connect flanges l0 and H, the wire being .sub-

stantially straight except for an upward bend as indicated. The template wire 2| extends from flange l3 to point 22 on wire .20, at which point a Y pipe connection is to be formed. The template wire 23 is bent in arcuate shape at a portion thereof to avoid the obstruction 2l,--wire 23 being joined to wire 25 by U bolts 26. In the arrangement illustrated, the flanges l0, I3 and I4 are to be secured to correspondingly disposed flanges of'pipes to be installed between bulkhead l2 and deck l1; and the pipe to be installed between fitting I5 and pipe I9 is to contain a flangefor attachment to flange 18, and istobe butt-welded to the terminal of pipe l9.

According to 'my invention, the template wires are centered in position by centering fixtures such as 21 and 28, clearly illustrated in Figures '4 and 5. For securing a-wire, such as the template wire 20, in properly centered relation with respect to a flanged pipe such as H, the fixture 27 is used, this containing a solid body portion with a central aperture 29 extending longitudinally therethrough and an externally threaded boss 30 extending axially therefrom. The aperture 29, which extends also through boss 30, is

adapted to receive a terminal portion of the wire 20, which is held in place by the set screw 3| extending transversely into the fixture 21. A thin disk 32, preferably of sheet metal, is attached by bolts 33 to the bulkhead l2 and flange l0,said disk containing holes 34 therein adapted for registry with correspondingly disposed holes in thesaid bulkhead l2 and flange ID. The central portion of the disk 32 also contains a hole through which the boss 30 extends,the nut 35 being operatively mounted over boss 30 and held in abutment against disk 32 to maintain the fitting 21 with the template wire 20 in proper centered relation with respect topipe H. In substantially similar manner, the centering fixtures 36 and 31 are employed for securing the wires 20 and 2| in centered relation with respect to fittings l5 and IS.

The centering fixture 28 contains a cylindrical portion 38 mounted over the outer surface of pipe l9 and held in detachable engagement therewith by the set screw 39 extending transversely through the wall of the cylinder. Extending axially from the fixture 28 is the boss 40 containing an axial aperture ll adapted to receive the template wire 25 which is held in place by the set screwfl extending transversely intosaid boss 40. This arrangement is particularly adaptable for use with an arrangement of butt-welded pipes, as distinguished from the flange arrangement hereinabove described. Should it be desired to eliminate the use of a set screw like 39, or should the pipe equivalent to pipe l9 contain a threaded outer surface, the centering fixture 43, (Figure 6) substantially similar to fixture 23, can be employed. It will be noted that this fixture also contains a central aperture 44, with the cylindrical wall 45 being provided with a threaded portion 46.

In order to efiect a Y joint, such as is indicated in Figure 2, the adjustable clamping disk 41 is I employed. This consists of a fiat member containing in the body thereof a plurality of slots, preferably of arcuate configuration. In the form of diskillustrated, the slots 43 are disposed along a plurality of concentric circles, being in staggered' relation. In the pipe layout shown, the wire 20 is extended diametrically along the disk and is held afiixed thereagainst by the two oppositely disposed U bolts 49. Said U bolts are of conventional construction, the two legs of which flank the wire, and extend through the adjacent slot on the disk, the cross piece 50 being positioned over the legs of the U bolt and held secured. in place by the nuts 5!. template wire 2| is held in place by the two U bolts 52. It will be observed that in the preferred arrangement each of the wires is held clamped in place by at least two bolts, to effect a secure attachment to the disk 41.

Due -to the staggered arcuate arrangement of slots 48 in concentric-circles, it is obvious that any desired angular relation can be obtained between two template wires such as 20 and 2|, to conform with any desired pipe juncture. Furthermore, with the use of this device, there is no necessity whatsoever of permanently securing the wires 20 and 2| together, such as by welding, as is conventionally done. The wires can readily be adjusted in place in any desired relation, and the entire unit can be carried to the work shop for making the actual pipe connections from the" templates. Should it, howeveri be found that the" size of the templates will render it inconvenient to carry the entire disk and attached wires'as a Similarly, the

unit, the disk 41 and wires 20 and ii be appropriately marked to indicate the relative positions of the wires, and then disassembled (or convenient transportation. Thereafter, they can be readily reassembled into the exact positions as indicated by the markings.

It is of course obvious that the disk 4'! can be employed not only for the wire connection illustrated in Figures 2 and 3, but for T connections and other forms of pipe junctures, as well as for the bending of template wires into the predetermined shapes.

Figures 7 and 8 illustrate means of centering a template wire 53 with reference to a wall 54 through which a pipe is to extend. A circular are 55 is burned through the wall, leaving only the solid portion 56 for holding the cent al portion 5! in place. -The centering'fixture 58 is then inserted through a hole in the center of portion 51, and held in place by the nut 59 in threaded engagement with the boss 60 of the fixture. The template wire 53 can then be extended to any other desired point to conform with the layout of the pipe intended to extend through the wall 54. Thereafter, when the pipe is ready to be installed, the'arc 55 is extendedthrough portion 56 to remove the entire portion51, leavin g an opening through which the pipe canextendp It is of course understood that the various'embodiments above-described and shown inthe drawing are illustrative of my invention and not employed by way of limitation, inasmuch as nu-v merous changes and modifications may be made within the scope of the appended claims without departing from the spirit of this invention.
